Cl. 83308 3 Claims ABSTRACT OF THE DISCLOSURE A cut off devicefor ingots from a continuous casting machine in which two blades aremounted on opposite sides of the path of the ingot, one blade beingmounted on a movable block capable of travelling in guides on a frametoward and away from the path of the ingot, the other blade beingmounted on a plunger rod extending from a power cylinder to be movabletoward and away from the path of the ingot. The cylinder and the movableblock being secured together. The frame being pivoted at one end to afoundation or the like and the other end of the frame being supported byan extensible and retractable device so that the cutting blades, whenengaged with the ingot to cut it, can move with the ingot and bereturned to its original position to make a subsequent cut.

The present invention relates to metallurgy, and more particularly todevices for cutting moving ingots, especially those formed by continuouscasting.

The known devices for cutting moving ingots comprise cutting bladesmoving perpendicularly to the direction of movement of an ingot, one ofsaid cutting blades being fastened on a rod of the impulse chamber withan energy carrier (such as gunpowder, gas, air hydraulics), whileanother, the counter blade, is fastened on a movable block mounted on aframe common with the chamber.

A disadvantage of the conventional devices is the fact that the bladescutting into the ingot are entrained by the latter in the direction ofits motion, which results in the jamming and breakdown of the blades andalso in breaking the parts of said device.

An object of the present invention is to provide a device for cuttingmoving ingots, preferably those obtained in a continuous casting method,in which the blades after each cutting of the ingot should freelydisengage from the ingot without either jamming or breaking.

According to these and other objects, we claim a device for cuttingmoving ingots, preferably those formed in a continuous casting machine,in which the cutting operation is effected by means of blades movingperpendicularly to the direction of movement of the ingot, one of saidcutting blades being fastened on a rod of the chamber containing theenergy carrier, while another, or the counter blade, is fastened on ablock mounted on a frame common with an impulse chamber, with said framebeing mounted in such a way as to be capable of moving during theprocess of cutting the ingot in the direction of its movement.

"ice

To effect the movement of the frame and its return in the horizontalposition, it is expedient to articulate one end of the frame with arigidly fixed support, while the other end must be suspended on amovable balancing support which may be made in the form of a powercylinder, for example, hydraulic, which operates synchronously with therod of the impulse chamber.

The present invention will become more fully apparent from aconsideration of the following description of one of the possibleembodiments of the device for cutting moving ingots, taken inconjunction with the appended drawings, in which:

FIG. 1 is a schematic diagram showing a side elevation view of thedevice according to the present invention; and

FIG. 2 is a vertical cross-sectional view of elements 4, 5 and 6 of thedevice of FIG. 1.

On the frame 1 of the device and perpendicular, to the direction of themovement of the ingot 2, are mounted the impulse chamber 3 and a block,consisting of a stationary plate 4 (FIG. 2) and a movable plate 5,separated with a damper 6, for example a pack of rubber. The movableplate 5 is connected with the chamber 3 by means of rods 7.

On a rod 8 of the chamber 3 and on the movable plate 5 of the blockcutting blades 9 and 10 are fastened. The chamber 3 and the movableplate 5 of the block are mounted in such a manner as to be capable ofmoving along guides 11 of the frame 1. One end of the frame 1 isconnected by means of a hinge joint 12 with a rigid support 13, whilethe other end is suspended on a rod 14 of a power cylinder 15 operatingin a synchronous manner with the rod of the chamber 3.

The movement of the frame upwardly is limited by a rest 16.

The device is provided with systems for return of the moving parts totheir initial position (not shown).

The device functions as follows.

After placing the movable parts of the device into their originalposition in relation to the axis of the ingot 2 energy is supplied to 3and the energy carrier is admitted, thus moving the rod 8 with thecutting blade 9 in the direction of the ingot 2.

Simultaneously with the movement of the rod 8, the chamber 3 which isnot rigidly fixed to the frame 1, under the action of reaction forces,is moved along the guides 11 of the frame in the direction opposite tothat of movement of the rod 8.

Due to rods 7 connecting the chamber 3 with the movable plate 5 of theblock, said plate together with a cutting blade 10 fastened thereon,will be moved in the same direction as the chamber 3, thereby ensuringthe movement of the cutting blade 10 against the blade 9 fastened on therod 8; the ingot 2 is cut at the moment when the cutting blades 9 and 10meet.

Then systems operate for returning the rod 8, chamber 3 and the movableplate 5 of the block into their respective initial positions.

At the moment the cutting blades 9 and 10 cut into the moving ingot 2,the frame, under the pressure of the ingot on the blades, turns aboutthe hinge joint 13 in the direction of movement of the ingot, therebyinsuring the movement of blades in synchronism with that of the ingot,which prevents blades jamming in the ingot and breaking.

After the blades withdraw from the ingot, the frame 1, under the actionof the power cylinder 15, returns in its initial position until itthrusts against the rest 16. Then the cycle is repeated.

We claim:

A device for cutting moving ingots, especially those obtained by acontinuous casting method, comprising a frame, guides on said frame,said frame being mounted so as to be capable of moving during theprocess of cutting an ingot in the direction of the movement of theingot; an impulse chamber mounted to travel along said guides andprovided with a rod movable parallel to said guides; a block mounted onsaid frame consisting of two plates, one plate being stationary and theother plate movably mounted to travel along said guides; connecting rodsfor connecting said impulse chamber with said movable plate; and a pairof cutting blades, one blade being fastened on said rod and the otherblade being fastened on said movable plate.
